Rookie RB Toby Gerhart will miss the Vikings’ OTA next week, and minicamp in June is in jeopardy too, thanks to Stanford’s mid-June graduation ceremonies. NFL rules prohibit draft picks from participating in anything more than a rookie minicamp before their school’s graduation.

The real pressure point of the first round is coming in the second quarter, with picks 8 through 12 all unsigned to this point. That span includes the player who has been absent from his camp the longest thus far — defensive end Aaron Maybin has missed the Bills’ first week of practice. It also includes a wide receiver who many believed would go in the top five (Michael Crabtree of the 49ers) and the first running back selected in the draft (Knowshon Moreno of the Broncos).

Coach Mike Tomlin, defensive coordinator Dick LeBeau and director of football operations Kevin Colbert were among the representatives from the Super Bowl winners at the Ohio State Pro Day in Columbus, Ohio.

NFL coaches, scouts and GMs are traveling all over the country in March and April to get one more chance to see draft prospects up close at their college “pro days.” NFL.com will take you there as well, providing the most up-to-date results of drills and workouts – whose stock rose, whose stock fell, and who was there to witness it.
